Andrew asked me to relook at this patch, and it turns out to be pretty
messy, I should have never applid it.

You have a lot of checkpatch warnings and errors, and you are creating
new sysfs files with no documentation at all as to what you are doing,
and why you are doing it.  sysfs binary files at that, which should not
be used by ANY code that is trying to intrepret the data being sent to
those files, sysfs binary files are for "pass-through" mode only.

So please redo this patch, cleaning up all of the warnings and errors,
and use the standard kernel interfaces for this type of stuff (i.e. not
sysfs binary files.)

I've reverted it from my tree now, sorry.
